APPARATUS FOR COILING METAL RODS.

SPECIFICATION forming part of Letters Patent No. 426,067, dated April 22, 1890. Application filed April 1, 1889. Renewed January 30, 1890. Serial No.338,603. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY ROBERTS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Coiling Metal, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical longitudinal section of apparatus embodying my invention. Fig. 2 is an enlarged vertical section of the coiler. Fig. 3 is a horizontal section on the line III III of Fig. 2.

Like symbols of reference indicate like parts in each of the figures.

The object of my invention is to provide means for coiling rods as they are delivered from the finishing-rolls of the rod-mill; and it consists in certain new constructions and arrangement of the parts of the apparatus, hereinafter described, and particularlyindicated in the claims,

In the drawings, 2 represents the final set or pair of rolls of a rod-rolling mill, and 3 is the rodfwhich is shownpassing through the rolls in the direction of the arrow.

The coiler B consists, essentially, of a rotary cone, which receives the metal rod at its smaller end or apex and distributes it in a coil at the exterior of its periphery at the larger end. For the purpose of more easily governing and controlling the rod in its distribution I prefer to surround this cone with an outer concentric cone or shell fixed to and rotary with it; but, broadly considered, my invention is not limited thereto, but consists in a rotary distributing or coiling cone as distinguished from rotary tubes heretofore suggested for use in coiling rods.

In this specification I do not use the word cone in its strict mathematical sense, but use it generically, meaning thereby a tapering body, whether it be truly conical or not.

I prefer to make the coiler of two concentrically-arranged shells -l and 5, which are conical in form and are somewhat separated, as shown in the drawings, being connected by a rib 6, which is between the shells, being preferably cast integrally with one and bolted to the other, and which extends downwardly, preferably in an inclined or spiral line. The outer cone 5 extends somewhat above the inner cone 4, and at the top is provided with an open end situate at the extremity of a guide trough or tube 7, which leads from the delivery side of the rolls and which is preferably made in sections, so that it may easily be removed and repaired. The double cone constituting the coiler is rotary on its vertical axis, being journaled in bearings bin aframe or housing 8, and is provided with an external encircling gear-wheel 9, the teeth of which are in gear with a pinion 9, which is rotated by means of a belt-pulley 10. The gear-wheel is supported in its rotation by means of supporting wheels or rollers 11.

In using the apparatus the rod may he coiled upon any suitable receiving-surface beneath the coiler B 5 but for convenience in removing the coil I prefer to employ as the receiving surface the bed or frame of a truck 12, which is mounted 011 an inclined track 13, leading under the housing 8. \Vhen the truck is in position beneath the coiler, it may be lifted from the track nearly to the level of the mouth of the coiler by lifting-rods 14:, which are moved vertically by means of a foot-lever 15. Then the rod has been coiled thereon, the truck may be lowered upon the track by moving back the lever 15, and when it is on the track the truck will automatically travel by gravity along the same away from the coiler.

The operation of the apparatus is as follows: The rod as it comes from the finishing-rolls passes through the guide trough or tube and enters the open upper end of the coiler, which is rotated in its bearings by the gearing above described, and by the apex of the inner cone is directed into the space between the cones. The rotation of the apparatus causes the rib to engage the rod, and as the rod is fed from the rolls said rib will distribute it in a regular coil upon the surface of the supported truck. The inclination of the rib 6 assists in distributing the rod evenly, and by preventing an abrupt bend at the point where the rod leaves the cone it avoids danger of kinking or bending. lVhen the rod has been coiled, the truck is lowered upon the track, as before explained, and by gravity it moves along the track away from the housing, leaving the Way clear for another truck to be put in place.

The advantages of my invention will be appreciated by those skilled in the art.

The apparatus is simple in construction, is

I durable, and is very efficient in performing the Work for which it is intended.

I claim 1. In apparatus for coiling metal, a rotary receiving and coiling cone having a channel which receives the metal at the smaller end or apex and delivers it at its base, in combin a- 3. In apparatus for coiling metal, a rotary double hollow cone separated by a peripheral space through which the metal passes, substantially as and for the purposes described.

4:- In apparatus for'ooiling metal, the combination of a rotary hollow double cone, a peripheral gear-wheel attached thereto, and a driving-pinion, substantially as and for the purposes described.

5. The combination, with a coiler, of an inclined track, a car or truck, and a car-lifter under the ooiler, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 29th day of March, A. D. 1889.

HENRY ROBERTS.
